  • A coupling is a pipe fitting used to stop leakages in broken or damaged pipes. The pipes to be connected should be of the same diameter. The two kinds of couplings used in plumbing are regular coupling and slip coupling. The basic function of Couplings and Union is simply to connect two pieces of pipe or tubing. Therefore, couplings and unions are generally quite short fittings. The regular coupling is arranged between the two pipes to prevent further leakages with the help of rubber seals or gaskets on the both sides. The slip coupling itself contains two pipes to repair the damaged lengthy pipes.
  • pipe coupling is any fitting or device used to join two or more pipes in such a way that continuity is maintained between them. The body of a pipe coupling is typically made of the same or similar materials as those used to construct the pipes it joins. They may be rigid or flexible depending on the amount of movement the pipe is subjected to and may be permanent or removable fixtures. A pipe coupling can be stepped or reduced in internal diameter to accept pipes of different sizes, be T or cross shaped to join more than two pipes, or angled to form bends. Pipe couplings may also include peripheral features or equipment such as inspection openings, flow meters, or valves.
  • Socket Weld Half Coupling Pipe Fittings are used for fluid conduits in which each end portion of two tubes to be connected is provided with a swaged-on adapter carrying the necessary means to connect or disconnect the tubes without disturbing the swaged-on adapter.
    Socket Weld Half Couplings are highly demanded in the pipe fitting market. SW Half Couplings are fittings that help to extend or terminate pipe runs. These fittings are also used to change pipe size. SW Half Couplings extend a run by joining two lengths of pipe. They are known as reduced coupling if they are used to connect pipes of different sizes. Couplings are also known as repair couplings. These couplings are without stops or ridges and they can be fixed anywhere along the pipe length for preventing leak of any kind.

  • Pipe fittings are used to connect pipes or tubes in two ways:
    • By threading: Threaded pipes screw together to connect or join. Generally metal pipes are threaded and they have threaded fittings.
    • By slip fit: Slip fit pipes use sleeves that slip into one another. The plastic pipes are either threaded or slip fit.
